I've recently been getting seemingly random bluescreens that I can't associate with any particular application or device. The error message is always the same.

IRQL_NOT_LESS_OR_EQUAL
0x0000000A (0x0000001C, 0x00000002, 0x00000001, 0x806E6A16)

I'd be very appreciative if somebody could take a look at a few recent minidumps and tell me what to suspect.

Thanks.

All three of your errors are 0xA and these are strong indications of hardware issues but they can also be caused by a driver attempting to access an IRQ Level it has no right doing.

In your case it is the afwcore.sys which is an Outpost firewall driver. Google this driver and you'll find al ot of people have issues with this driver especicially with dual core cpus and Vista.

That is helpful, thanks. I'll try upgrading Outpost to the latest version and if that doesn't solve my problem I'll switch to something else.
